EXTENSION-TABLE.

Speccation of Letters Patent.

To all Lc/tom t may concern.'

Be it known that I, Gann NELSON, a citizen of the United States, and a resident of Toledo, in the county of Lincoln and State of Oregon, have invented an Improvement in EXtension-Tables, of which the following is a specification.

My invention is an improvement in eX- tension tables, and has for its object to provide a table of the character specified, wherein the intermediate or filling leaves are sectional, and the sections are hinged together and to the table in such manner that the sections may be folded upon each other and dropped downward within the frame of the table to permit the end sections to close together, and wherein folding legs are provided arranged to unfold when the table is extended to support the ends of the table, and wherein other mechanism is provided for locking the intermediate sections in unfolded position.

Figure 1 is a perspective view of the improved table in closed posi-tion,

Fig.. 2 is a sectionron the line 2 2 of Fig. 1,

Fig. 3 is a perspective view of the table extended and with the intermediate leaves partially unfolded,

Fig. /l is a section on the line d et of Fig. :2.

Fig. 5 is a bottom plan view of the table extended,

Fig. 6 is a perspective View of the hinge connection between the intermediate leaf sections,

Fig. 7 is a section on the line 7 7 of Fig. 6,

Fig. `8 is a section on the line 8 8 of Fig. 2 with the sections in folded position,

Fig. 9 is a section on the line 9 9 of i Fig. 5 looking in the direction of the arrows adjacent to the line, i

Fig. 10 is a perspective view of the legs detached,

Fig. 11 is a similar view showing the locking mechanism for the intermediate leaf sections, and

Fig. 12 is a perspective view of the hinge for connecting the intermediate sections to the table frame.

ln the present embodiment of the invention the table consists yof end leaves 1 and intermediate leaves, said vend leaves being connected by the usual slides 2, 2a and 2b, so

' that they may be moved apart from each other to permit the insertion of intermediate y of three sections, namely, a central section 7 and lateral sections 7a, the lateral sections being hinged to the side members of the frame, while the central section is hinged to the lateral section. Each of the lateral sections of each leaf is connected to the adjacent side member of the frame by means of the hinge shown more particularly in Fig. 12. Each of the said hinges consists of a leaf 8 which is secured to the upper side edge of the frame, by means of screws or the like, and a leaf consisting of two portions 9 9a. The portion 9a of each hinge leaf 9 92L is offset from the leaf 8 and con nected thereto by the portion 9, which is at an obtuse angle with respect to the portion 9a. The portion 9a is secured to the under side of the leaf section by screws or the like, and the leaf 8 and the portion 9a of the leaf 9 9a are countersunk in the sections.

It will be noticed from an inspection of Fig. 4: that the upper sides of the frame 6 are spaced below the upper edges of the slides 2, 2a and 2b, a distance such that when the sections are turned outwardly to lie upon the slides, the portions 9 ofl the hinges will space the leaf sections at the proper height to permit the sections to lie in the same plane and in the plane of the top of the leaves 1. The central section 7 of each intermediate leaf is connected to the lateral sections by the hingerconstruction shown more particularly in Figs. 6, 7 and 8. The said construction comprises plates 10 and 11 which are counter'- sunk in the side edges of the leaves 7 and 7a. A. hinge bar 12 is pivoted at one end to the plate 10 as indicated at 13, and the opposite end is connected to the plate 11 by a lost motion or sliding connection indicated at 14. The arrangement is such that when the lateral sections of an intermediate leaf are turned upward and outward to lie upon Fatented Oct. 16, 1917.

the slides, the central section will belifted into the plane of the lateralvsections,-.-and when the lateral sections are folded inwardly, one upon the other, the `central e section will be lowered into a position beneaththe lateral sections.

Each of thebars 12 before mentioned, is cut away at its upper outer--corneras indicated at 1G, te engage ay stop pin 17 on the plate 10 to flimit ther swinging motion of the said bar, with respect to the section 7 to which it is connected, to cause the bar to swing upwardly at its inner end when the .section 71 is swung upward and downwardly to lift the central section into the plane of the lateral'section. Either lateral section may befolded inwardly, and buers 15 are arranged on thel under sides ofthe said `lateral sections to prevent them striking each other, when they are folded. These buffers may be of any suitable materiahas for instance, rubber.

The sections of the intermediate leaves are 'loclred at one end to the table, in the same plane and in the plane ofthe tops of the yend sections 1, by means of locking plates 1S on the outer slides 2b of each side, which engage beneath headed lugs 19 on the lateral sections Vwhen `the leaves 1 are pressed `toward each other afterV the intermediate leaves'hare been extended. At the other end of the table the intermediate leaf sections are locked by locking plates Q0 which are mounted upon spring'plates 21, secured to rigid bars 22 on the section 1 at the said end. These spring plates are so arranged that they may swing inwardly, but are limited in their outward swinging movement by extensions 23 fromthe blocks, the saidL extensions fitting the outerfaces ofthe plates. These loclzingfplates enffage beneath headed lugs 24 on the sections, the said lugs being similar tothe lugs 19 before mentioned.

ln order to extend the table from the position of Figs. 1 andv 2, the sections 1 are drawn away from each other until they,1 oc# cupy vthe position shown in Fig. 3. The folded intermediate leaves are now Visible and accessible and they are unfolded as in* dicated inFig. 3, until'all ofthe sections of the intermediate leaves are Ain the same plane andinthe plane of the tops of the leaves 1. The sections 1 when being eX` tended are withdrawn `from each other a slightly greater distance than the aggregate width of theintermediateleaves, inV orderthat the said rleaves 7 7 may be unfolded without interfering with the dowel pinsk 25 whichfare on the inner edges ofthe tops of the leaves 1 and which are adapted to engage openings 'inthe edge of the opposite section whenl the -table is contracted, and to engage other openings?? in the outermost oftheintermediate leaves when the table iseXtended. After the intermediate leaves have been ,unfolded as above mentioned, the sections 1 are moved. toward yhot-'her slightly, sufficient to engage the dowel pins in the openings in the edges of the intermediate leaves, and the top is vin condition for use.

'ln order that rthere `may be no danger of binding or sticking, due to dampness or the like, between the intermediate leaves, the .75 hinge leaves Vand 9 9a .are .connected `in the manner shown inFig. 12. The-portion v 9 of the leaf @e192 Aand .the :leaf l8 Ahave bearings'which are adapted .to alineand Y intel-engage vto receive ya lpintleQQ, `and it Y will be noticed that the bearings of `the leaves are spacedapart slightly .so that the hinge Vleaves may Amove. slightly with frespect to each other, longitudinally of the pintle; 'Thus should lfor any reason 'the leaves bind at-their-adiacent edges,ftheout ermost leaves maymorey away from 4the central leaf to `compensate ffor such binding and to `permitthe free movement -of the leaf sections with respectrto each other. e@

A pair ofl folding legslis arrangedat'each end of the table Ato support fthe vsaid :end whenthe table iseXtended. VThe legsfSOof each pair are secured near their'upper ends to hinge bar 31. This'hinge barlis con. e nected by hinges 32 to hinge blocks mounted --on the slidesA 2- at `one Aend .of :the table, and the slides@b attheother end.

lt `will be noticed from .an inspection of Figs. 9 and 10 that each leg is extended aber-fe the hinge bar 31 .asindicated at 84, a sulhcientdistancesuch that the upperend of the extension will engage `beneaththe top of the yadjacent leaf 1 when thejlegs are unfolded, that is, when they occupy the fullline position of AFig. v9. Stop-blocks 35 are arranged in position such that A.when the legs `are .unfolded in the r.full ilinei-position ofFig.9,the extensions .34 -will-hfengage the said blocks to prevent fair-ther swinging Amovement ofthe 'legsuoutwardly at their lower ends, and a spring lockais provided for each pair of flegs forilocking theflegsin unfolded position. i Eachof-these'flocks 36 visfin the :form of a spring plate secured `to;y the top of .theileaf i1, the Vfree end of the plate 'being ybent .outwardly away-from` the topandbeing spaced apart from the adjacent stop blocl 35,just arenough 4to permit theeXtensiom :after it is passedA over fthespringplatefto .move in between the free end of the playtefandl the stop block. lt willl beevident fromthedescription, that vthe 4flock-36willfholdthe legs in unfolded position until thefsaidilockisjre leased by depressing the same. I'llhefOlding legs atveaclrendoflthe tableare automatically folded vby Jth,e.contracting ofthe itable. xt will.bernotieedffromfaninspectionoflFig. 5,-fthat: the legs ofeachpair arev in register .away from each other.

and that they are also in register with the side members of the frame 6.

It will be evident that when the intermediate leaves are folded and the sections l are moved toward each other, the extensions 34 will engage the ends of the side members of the frame 6, and the said extensions will be forced outwardly swinging the lower end of the. legs inwardly and folding the said legs upon the plate 4, as shown in Fig. 2. The legs are also automatically extended when the table sections l are moved outward This extension is brought about by links 37 each of which are pivoted to the extension 34: of one leg of the pair, and each link passes at its inner end through a loop 38 on the frame 6. The inner end of each link is bent outwardly, as shown at 39, to prevent disengagement of the link, and the links are of such length that when the end leaves l are almost fully extended, the lugs 39 will engage the loops 38, and will swing the legs into unfolded position. Thus no attention is required in extending the top to unfold the legs, and it is only necessary to release the spring lock 86 in order that the legs may automatically fold.

it will be noticed from an inspection of Fig. 5, that the spring plates 36 are auto matically released by the links 37. Each of these links is provided at its outer end with a cam portion 37a, which is so arranged that it will depress the spring lock to permit the legs to fold.

Vhen the intermediate or folding leaves are folded, the sections l of the table are first drawn yaway from each other to release the pins. The links 37 are held by the frame, and portions 37a of the links will depress the springs 36 as the legs are drawn outwardly with the end sections.

I claim:

1. An extension table comprising end leaves having legs, a pedestal, oppositely arranged series of slides connecting the leaves and the pedestal, a substantially rectangular frame connected with the pedestal between the series of slides, intermediate leaves connected with the frame between the end leaves, each intermediate leaf consisting of a central and lateral sections, the lateral sections being hinged to the side members of the frame to fold outwardly into the plane of the end leaves or inwardly upon the central section, a swinging connection between the lateral sections and the central section of each intermediate leaf for swinging the said section up in the plane of the end leaves when the lateral sections are swung outwardly into the plane of the said end leaves, means in connection with the lateral sections and the end leaves for locking the said intermediate leaves in extended p0- sition when the end leaves are moved into contact with the outermost intermediate leaves.

2. An extension table comprising end leaves having legs, a pedestal, oppositely arranged series of slides connecting the leaves and the pedestal, a substantially rectangular frame connected with the pedestal be tween the series of slides, intermediate leaves connected with the frame between the end leaves, each intermediate leaf consisting of a central and lateral sections, `the lateral sections being hinged to the side members of the frame to fold outwardly into the plane of the end leaves or inwardly upon the central section, a swinging connection between the lateral sections and the central section of each intermediate leaf for swinging the said section up in the plane of the end leaves when the lateral sections are yswung outwardly into the plane of the said end leaves.
